The concurrent rise in commercially available small form-factor, low-power, x86-based processors creates the possibility of incorporating General Purpose Processor (GPP) software radios into existing sensor networks. The eStadium VIP project is considering the addition of such nodes to sense digitized RF spectrum data in Bobby Dodd football stadium. The flexibility inherent in GPP software radio provides rapid algorithm testing; however, the hardware is often large, heavy, and power intensive. Due to the limited resources and practical considerations in the stadium, the trade-offs between size, weight, area, and power (SWAP) requirements and SDR capabilities must be studied prior to deployment. A performance analysis across four PC form factors, including one suitable for embedded use, running realistic SDR applications is presented. Case studies include FM radio with the BPSK modulated Radio Broadcast Data Service (RBDS), FM analog video, and distributed processing of digital video with QPSK modulation. Such studies provide valuable insight into SDR testbeds.","PeriodicalId":239177,"journal":{"name":"Workshop on Wireless Network Testbeds, Experimental evaluation & CHaracterization","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121365085","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We leverage the NS-3 LENA module, which allows researchers to conduct simulations by emulating large network of base-stations, mobile devices and core network. However, the validity of results produced from such simulations is limited due to the physical layer model and may not accurately reflect the true behavior of densely-deployed LTE networks. Hence, we implemented selected LTE physical channels in LabVIEW to facilitate more realistic emulation of the LTE testbed and integrate it with MAC/higher layers of LENA protocol stack. The main goal of the testbed is to be able to show the artifacts caused in interference limited environment and demonstrate the performance of Enhanced Inter-cell Interference Coordination (eICIC) algorithms proposed by researchers in 3GPP. This demo shows preliminary results and we plan to use this testbed to showcase different aspects of Software Defined Networking (SDN) framework which is used to fine-tune different aspects of dense deployments within EU FP7 CROWD research project.","PeriodicalId":239177,"journal":{"name":"Workshop on Wireless Network Testbeds, Experimental evaluation & CHaracterization","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124410718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, spectrum sensing is employed, in order to monitor spectrum occupancy and drive appropriate adaptation decisions. Researchers in the field primarily evaluate proposed sensing approaches in terms of detection accuracy and efficiency of free spectrum utilization. In this work, we focus on online assessment of spectrum occupancy with respect to sensing delay and energy efficiency. Evaluation of spectrum sensing methods with respect to these two metrics is rather lagging in recent experimental developments. The first is related to the latency induced by the spectrum sensing process and its impact on sensing efficiency, which is tightly connected to the resulting performance of the cognitive solution. On the other hand, energy consumption is considered as a crucial issue in all types of wireless communications. Therefore, it is important to extend existing testbed experimentation tools and develop new ones, in order to equip cognitive testbeds with such advanced monitoring capabilities. To this aim, we integrated the proposed monitoring procedure with the experimentation tools of the CREW testbed federation. In order to demonstrate the applicability of our framework, we experimentally validate the performance of four different sensing platforms, as well as a real-time spectrum sensing engine that implements parallel processing on software defined radios, in terms of the aforementioned metrics.","PeriodicalId":239177,"journal":{"name":"Workshop on Wireless Network Testbeds, Experimental evaluation & CHaracterization","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132039607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Delay Tolerant Networks~(DTNs) enable content distribution in such areas, using mobility of devices and avoiding the need for traditional network infrastructure. In DTNs, data is passed from mobile device to mobile device, whenever possible, in an intelligent way. DTNs have the potential to reach out to under-served regions where cellular Internet access (3G, LTE, and beyond) might be expensive or unavailable. We are interested in DTNs for distributing media from cities to under-served rural areas. The content is distributed to the target destinations, using either public transportation or commuting vehicles such as taxis, equipped with wireless DTN-enabled devices. At each target destination, a micro-entrepreneur business is established with the help of our network: Micro-entrepreneurs use DTN-enabled projectors (also referred to as cinemas-in-a-backpack) to deliver entertainment content at low cost, and exploit the opportunity to create a micro-business around the show events. In this paper, we introduce the DTN system setup, present performance results of laboratory tests and test with a local commuter train of periodic and predictable mobility. Further, we present the target scenario and specific technical challenges. We aim to explore opportunities for a rural, under-served region in the north of Pretoria, South Africa.","PeriodicalId":239177,"journal":{"name":"Workshop on Wireless Network Testbeds, Experimental evaluation & CHaracterization","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129181284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This has led to rapid emergence of heterogeneous wireless technologies that share the RF spectrum in an un-coordinated way. Such a coexistence introduces high uncertainty and complexity to the medium, affecting reliability and availability of wireless net works. This problem aggravates for technologies operating in the lightly regulated, yet crowded ISM bands. To address coexistence of different technologies in the scarce RF spectrum, provide proper interference-aware protocols, and mitigation schemes, we need to develop a good understanding of the interaction patterns of these technologies. In this paper, we provide a thorough study of the implications of Cross Technology Interference (CTI) on the particularly vulnerable low-power IEEE 802.15.4 wireless networks. We identify the underlying vulnerabilities that hamper 802.15.4 to withstand CTI. We show that the uncertainty that CTI induces on the wireless channel is not completely stochastic; CTI exhibits distinct patterns that can be exploited by interference-aware protocols.","PeriodicalId":239177,"journal":{"name":"Workshop on Wireless Network Testbeds, Experimental evaluation & CHaracterization","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126977889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
